Campaign was enjoyable and a compelling back story on how Optimus become a Prime. But multiple sucks, the servers are horrid and if you are a higher level in multiplayer than your friends you will have a hard time connecting to them to play coop campaign.
It is a great game. The only thing I would have liked to seen would have been a co-op mode where you didn't have to be online to play it. I guess it would be called a couch co-op. Other than that the game was great.
